As you say, the rigid body frame components, can define the end points of the link. But what about "the flexible beam", how to define its endpoint? The "maplesim help" say "the beam is straight and its neutral axis is aligned with the x axis of the primary frame", then its deformation is measured. I think in a system, the flexible beam is used together with the rigid body frames, but it always point to the direction of the x axis,...

Thank you for your post! But I`m newbee in MapleSim and have one stupid question. Can you explaine how to compute the g-force magnitude and feeding it into the TSDA? May be, you post msim-file or screenshot?

I need to use the flexible beam in my model. I want to know if the component's correctness can be guaranteed, but I can't find any correlative documents or thesis, only find an article titled "Dymola – Flexible Bodies library". Is the flexible beam in maplesim similar to this? based on the modelica library? applied the finite element method? Some detailed information is very helpful.

I want to define the inertia matrix of a body within a subsystem as a subsystem parameter. I can define constants (like mass), but I cant define the 3x3 inertia matrix. It looks like MapleSim returns a dimensional error when I try to simulate the model. How can I assign the inertia of the rigid body to a parameter?

I am trying to create a Simulink component block from a MapleSim subsystem. I have one input to the subsystem, and the Specified Inputs and Outputs section of the MapleSim Connector worksheet also shows that the subsystem has one input. However, When I export the model to Simulink, there is no input port, just one output. How can I fix this?

Current I need model a mechanical system with kinematic loop. In Maplesim4 the calculation speed is too slow. I need to use this model in HILS. How to solve this problem? I check the 'four bar' example, It's too slow(simulation 1 second, 40second is needed, Intel xeon 3GHz,2cpu)
Anyone who can help me?
Thanks!

Who knows how to model a brushless dc motor? Can I use a synchronous machine and some circuits? Brushless dc motors do require rotor position information in order to select the appropriate commutation angle. Using three Hall sensors? But how to model a hall sensor or something which can specify the rotor's position and send out a signal? I am looking forward to your answer. If you have some experiences of modeling a double closed-loop dc machine using maplesim, please tell me too.
